Dangerous Behavior and Intractable Axial Skeletal Pain in Performance Horses: A Possible Role for Ganglioneuritis (14 Cases; 2014-2019).

Dangerous behavior is considered an undesired trait, often attributed to poor training or bad-tempered horses. Unfortunately, horses with progressive signs of dangerous behavior are often euthanized due to concerns for rider safety and limitations in performance. However, this dangerous behavior may actually originate from chronic axial skeleton pain.

Human rabies: prospects for elimination.

Almost half of all countries in the world are effectively free of human deaths from dog-mediated rabies. But the disease still affects people in low- and middle-income countries, especially the rural poor, and children. Successful regional elimination of human rabies is attributable to advances in significant and sustained investment in dog vaccination, post-exposure vaccination and surveillance, illustrated by productive efforts to reduce human rabies in Latin America over the last 35 years.

Effect of Azaperone on Induction Times in Etorphine-Immobilized White Rhinoceros (Ceratotherium simum).

We describe induction time in six white rhinoceros (Ceratotherium simum) when they received etorphine intramuscularly (IM) or etorphine plus azaperone IM. The median induction time was reduced from 8.9 min for etorphine alone to 6.

Colony Forming Potential and Protein Composition of Commercial Umbilical Cord Allograft Products in Comparison With Autologous Orthobiologics.

Background: Umbilical cord (UC) connective tissues contain plastic-adherent, colony forming unit-fibroblasts (CFU-Fs) amenable to culture expansion for potential therapeutic use. Recently, UC-derived allograft products have been made available to practitioners in orthopaedics and other specialties, by companies purporting "stem cell"-based healing. However, such marketing claims conflict with existing regulations for these human tissues, generating questions over the cellular and protein composition of current commercially available UC allograft products.

Microfracture Augmentation With Trypsin Pretreatment and Growth Factor-Functionalized Self-assembling Peptide Hydrogel Scaffold in an Equine Model.

Background: Microfracture augmentation can be a cost-effective single-step alternative to current cartilage repair techniques. Trypsin pretreatment combined with a growth factor-functionalized self-assembling KLD hydrogel ("functionalized hydrogel") has been shown to improve overall cartilage repair and integration to surrounding tissue in small animal models of osteochondral defects.

Hypothesis: Microfracture combined with trypsin treatment and a functionalized hydrogel will improve reparative tissue quality and integration as compared with microfracture alone in an equine model.

A RETROSPECTIVE ANALYSIS OF AMOEBIASIS IN REPTILES IN A ZOOLOGICAL INSTITUTION.

Amoebiasis is a significant protozoal disease of reptiles causing nonspecific clinical signs including diarrhea, anorexia, and lethargy. It frequently results in acute death. Investigation of the pathophysiology of amoebiasis in reptiles has been hampered by the inability to accurately identify amoeba to the species level using conventional techniques.

ANTIBODY PREVALENCE TO AFRICAN SWINE FEVER VIRUS, MYCOBACTERIUM BOVIS, FOOT-AND-MOUTH DISEASE VIRUS, RIFT VALLEY FEVER VIRUS, INFLUENZA A VIRUS, AND BRUCELLA AND LEPTOSPIRA SPP. IN FREE-RANGING WARTHOG (PHACOCHOERUS AFRICANUS) POPULATIONS IN SOUTH AFRICA.

The warthog (Phacochoerus africanus) can be used as a model for investigating disease transmission at the human, wildlife, and livestock interface. An omnivore and scavenger, a warthog moves freely between natural ecotypes, farmland, and human communities and is susceptible to diseases of zoonotic, agricultural, and conservation concern. A retrospective study using 100 individual serum samples collected from May 1999 to August 2016 was performed to determine antibody prevalence to seven pathogens in warthogs from five locations in northeastern South Africa.

Light chain myeloma and detection of free light chains in serum and urine of dogs and cats.

Background: Detection of free light chains (fLC) in animals relies on protein electrophoresis or the Bence-Jones protein test on urine.

Objective: To describe the detection of both serum fLC (sfLC) and urine fLC (ufLC) in 8 dogs and 2 cats using a commercially available human immunofixation (IF) kit.

Animals: Archived serum or urine samples from 27 dogs and 2 cats submitted to the Colorado State University Veterinary Diagnostic Laboratory for routine diagnostics.

Equine Cervical Pain and Dysfunction: Pathology, Diagnosis and Treatment.

Interest in the cervical spine as a cause of pain or dysfunction is increasingly becoming the focus of many equine practitioners. Many affected horses are presented for poor performance, while others will present with dramatic, sometimes dangerous behavior. Understanding and distinguishing the different types of neck pain is a starting point to comprehending how the clinical presentations can vary so greatly.

Progressive gammopathy and coagulopathy in a young English bulldog.

A restricted polyclonal or biclonal gammopathy resulting in bleeding tendencies was diagnosed in a young, neutered male English bulldog with concurrent splenomegaly, anemia, and severe elevations in IgM and, to a lesser degree, IgA immunoglobulins. There was a positive clinical response to treatment with prednisone and chlorambucil. This case bears similarity to a recently published syndrome of polyclonal gammopathy that is not neoplastic in origin in this breed.

Pupillary reflex and behavioral masking responses to light as functional measures of retinal degeneration in mice.

Background: Pre-clinical testing of retinal pathology and treatment efficacy depends on reliable and valid measures of retinal function. The electroretinogram (ERG) and tests of visual acuity are the ideal standard, but can be unmeasurable while useful vision remains. Non-image-forming responses to light such as the pupillary light reflex (PLR) are attractive surrogates.

SYSTEMATIC EVALUATION OF 106 LABORATORY REFERENCE DATA ARTICLES FROM NONDOMESTIC SPECIES PUBLISHED FROM 2014 TO 2016: ASSESSING COMPLIANCE WITH REFERENCE INTERVAL GUIDELINES.

Population-based reference intervals (RIs) are vital tools used to characterize health and disease based on laboratory values. The science and statistical basis for RI generation have evolved over the past 50 yr. Current veterinary-specific guidelines by the American Society of Veterinary Clinical Pathology exist for establishing RIs from nondomestic and wild animals.

Osteochondral regeneration using scaffold-free constructs of adipose tissue-derived mesenchymal stem cells made by a bio three-dimensional printer with a needle-array in rabbits.

Osteoarthritis is a major joint disease for which medical interventions have been extensively investigated in humans and animals. In this study, we examined the regeneration of articular cartilage and subchondral bone using a scaffold-free construct consisting of adipose tissue-derived mesenchymal stem cells (AT-MSCs) fabricated using a bio three-dimensional (3D) printer. AT-MSCs were isolated from three rabbits and cultured to a number of sufficient for creation of 3D-printed constructs.

Objective: To compare short- and long-term outcomes of dogs with adrenal tumors treated by adrenalectomy with laparoscopy or laparotomy.

Study Design: Retrospective study of dogs that underwent adrenalectomy with laparoscopy or laparotomy.

Sample Population: Fourteen dogs treated with laparoscopic adrenalectomy (LA) and twenty-six dogs treated with open midline adrenalectomy (OA).

Multiplex fluorescent immunocytochemistry for the diagnosis of feline infectious peritonitis: Determining optimal storage conditions.

Background: Feline Infectious Peritonitis (FIP) is a fatal disease of cats that can be very difficult to definitively diagnose antemortem. Multiplex fluorescent immunocytochemical (MF-ICC) assays are emerging as useful diagnostic tests in veterinary medicine, particularly for fluid samples.

Objective: We aimed to develop and optimize an MF-ICC assay to detect feline coronavirus within macrophages, with the primary goal of determining the allowable/recommended sample storage conditions for clinical use of this assay.

Intraobserver and interobserver reliability of mud scoring systems for use in cattle at slaughter.

At slaughter plants, live cattle are often scored for mud coverage as mud on hides can impact food safety and drives decisions regarding interventions during processing. Currently, there is no standardized method utilized to assess mud coverage. The aim of this study was to determine the intraobserver and interobserver reliability of 3, 4, and 5 point mud scoring systems.

The Effects of Parent Ages on Birth Defects.

Background: Men and women, in the United States, are having children at considerably older ages. This changing demographic has been associated with multiple neonatal adverse birth outcomes that are currently considered to constitute a major public health crisis. The objective of this study was to evaluate the risk of parent age on birth defects and to provide results that can serve as a starting point for more specific mediation modeling.

The risks of advancing parental age on neonatal morbidity and mortality are U- or J-shaped for both maternal and paternal ages.

Background: The biologic implications of delayed parenthood have been blamed for a major public health crisis in the United States, that includes high rates of neonatal morbidity and mortality (NMM). The objective of this study was to evaluate the risk of parent age on NMM and to provide results that can serve as a starting point for more specific mediation modeling.

Methods: Data containing approximately 15,000,000 birth records were obtained from the United States Natality database for the years 2014 to 2018.

Calpastatin Overexpression Protects against Excitotoxic Hippocampal Injury and Traumatic Spinal Cord Injury.

Small molecule inhibitors of calcium-dependent proteases, calpains (CAPNs), protect against neurodegeneration induced by a variety of insults including excitotoxicity and spinal cord injury (SCI). Many of these compounds, however, also inhibit other proteases, which has made it difficult to evaluate the contribution of calpains to neurodegeneration. Calpastatin is a highly specific endogenous inhibitor of classical calpains, including CAPN1 and CAPN2.

Absolute Erythrocytosis in a Sunda Wrinkled Hornbill ().

A captive, 22-year-old, intact male Sunda wrinkled hornbill () was presented for an acute onset of open-mouth breathing and bilaterally drooped wings. An external physical examination revealed a moderately thin body condition, marked respiratory effort, and a significant heart murmur. Diagnostic blood testing revealed moderate azotemia and persistent erythrocytosis, initially documented 2 years before this event.

The Nobel Mabel. The woman who discovered that low oxygen stimulates hemoglobin production.

The research of Mabel Purefoy FitzGerald (1872-1973) was recently recognized by Sir Peter Ratcliffe in his public lecture at the awarding of the Nobel Prize in Physiology or Medicine as a critical step in the recent delineation of the oxygen sensing pathway. This brief article offers a tantalizing glimpse into the life of a woman whose scientific career spanned four countries, worked with eminent scientists and clinicians including Haldane and Osler, and published important physiologic discoveries. Her accomplishments and astounding life were lost to history for more than one hundred years and it is time to bring her back.
